Crystal Springs Waterfowl Production Area is part of an extensive network of protected wetlands and uplands that support a rich diversity of wildlife. Acquired in the 1960s, it is one of thousands of Waterfowl Production Areas purchased with money generated from the sale of Duck Stamps. These lands are managed by the U.S. Fish and Wildlife Service to protect and restore waterfowl habitat. Created in 1934 as the federal license required for hunting migratory waterfowl, Migratory Bird Hunting and Conservation Stamps, known as Duck Stamps, became an important tool for wetland conservation. Each year, hunters must buy a Duck Stamp to hunt waterfowl, and the stamp’s design is chosen through an annual art competition. Duck Stamps also became popular with stamp collectors, wildlife art enthusiasts, and people who want to contribute to wetland conservation. Ninety-eight cents of every Duck Stamp dollar goes directly to purchasing or leasing wetland habitat for protection in the National Wildlife Refuge System.
